The selection principle of screw hoist in terms of components
Screw hoist is extremely widely used in cast iron gates. Because of its simple structure, easy installation, low price and other advantages, it is loved by the majority of users. However, if the device is not carefully selected, it will pose a great threat to the safety of the operator. So, how do we choose between the screw hoist and the device?
1. In the process of using the screw hoist, if there is no AC power supply, the alarm can be selected according to the DC power supply voltage used. For example, electric horns, transistor alarms, or those buzzers and other sounders, as long as they are in the limit switch, a contact rod type with a rated current of 5A can be used.
2. In the process of using the screw hoist, if you use a steel gate with AC electrical appliances and electric opening and closing, we can also choose electric horn, chang body tube alarm or buzzer in the selection process Yes, but for the alarm, we still determine the power supply according to the rated voltage of the selected alarm.
Whether it is on cast iron gates or on the selection of components of the screw hoist of steel gates, we need to pay great attention to it. Only when safety is ensured, we can work better.
